ATTACHMENT FOR LOCOMOTIVES.

Specification of Letters Patent.

Application filed May 3, 1920. Serial No. 378,672.

To all 7mm it may concern:

Be it known that I, J OHN B. RUsKosKr, a citizen of the United States,residing at New Iberia, in the parish of Iberia and State of Louisiana,have invented certain new and useful Improvements in Attachments forLocomotives, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to certain improvements in attachments forlocomotives, and it is an object of the invention to provide a novel andimproved attachment of this general character which is particularlydesigned and adapted for use in connection with a blow-off cock and itis anobject of the invention to provide a novel and improved attachmentofthis general character which may be advantageously employed at anytime for the purpose of driving off live stock which may have invadedthe right-ofway and thereby obviate to a large extent the destruction ofsuch stock.

It is also an object of the invention to.

provide a novel and improvedattachment of this generalcharacterincluding a source of liquid under pressure in the pipe leading from asource of liquid under pressure and delivering to a nozzle of a blow-offcock and wherein a valve is interposed in such pipe and operated throughthe instrumentality of the mechanism for'operating the valve of theblow-01f cock.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved devicewhereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

.Figure 1 is a. diagrammatic view in side elevation illustrating anattachment constructed in accordance with an embodiment of my inventionand in applied position;

Fig. 2 is an enlarged fragmentary view partly in section and partly inelevation illustrating in detail the means for operating the valvecomprised in my. improved attachment; and

Fig. 3 is a view similar to Fig. 2 showing certain of the parts in asecond position.

Patented Mar. 22, 1921.

As disclosed in the accompanying drawings, R denotes a running-boardwhich is usually provided adjacent a side of the boiler of a locomotiveand Bdesignates the blow-off cock of the locomotive boiler. The blow-offcock B is of a conventional type and the movable valve member thereof isprovided with a stem 1 operatively connected with the bell crank lever 2supported for rocking movement by the running board R. The bell cranklever 2 also has operatively engaged therewith a rod 3 leading to andoperatively connected to aulever 4', preferably arranged in the cab ofthe locomotive so that the blow-off cock may be readily opened or closedby-an engineman. Mounted upon the running boardR is a tank T,ofrequisite dimensions and which is eifectively maintained in appliedposition through the instrumentality of the brace members 5. 6 denotes apipe in communication with the tank T and which is adaptedto lead from asuitable source of fluid under pressure, such as air, hydraulic, orotherwise, as will com ply with the requirements of practice. The tank Tis also provided with a normally closed filling opening.

In communication with the tank T and preferably through the bottomthereof is a pipe 7, leading to and communicating with the nozzle 8 oftheblow-oif cock B. Interposed in the pipe 7; is a valve 9, preferablyof a rotary type and which has secured to an extended portion of thestem thereof an operating head 10 disposed in a direction toward. thestem 1 and terminating in a fork l1 straddling said stem 1. The stem 1,below the fork 11, is provided with a cross pin a, or the like which,after the stem 1 has been moved. upwardly apredetermined distance,contacts with the fork 11 and swings the rod 10 in a direction to movethe valve .9 into open position so that the liquid within the tank Twill be discharged through the nozzle 8 and which discharge ismaterially facilitated by the pressure imposed upon the liquid withinthe tank T. hen the stem 1 is moved to close the blow-off cock, the rod10 is automatically moved downwardly to close the valve 9 through theinstrumentality of the spring 12 interposed between the rod 10 and anoutstanding arm 14 carried by the .pipe 7 at a desired point above thevalve 9. The rod 10 is preferably provided with an upstanding member orfinger 15 slidably disposed through the arm 14 whereby the rod 10 isbraced and particularly against lateral movement in a horizontaldirection. The liquid within the tank T is preferably a chemicalsolution which will have quick action on the stock as it often occursthat the water discharged through the cock B under boiler pressure isinsuflicient to have the desired eifect upon the stock. Thesolutionwithin the tank is to overcome this disadvantage and by having the sameunder independent pressure, a proper or morev effective discharge of theliquid or solution is accomplished.

I also find it of advantage to interpose in the pipe 7 a globevalve 16sothat, when'desired, the flow through said pipe may be shut off orregulated.

It is also to be understood that the pressure upon the fluid within thetank T may be atmospheric and in which event, the top of said tank T isprovided with a suitable opening which may be readily attained bydisconnecting the pipe 6 therefrom. At this time, I wish to particularlystate that I do not wish to be limited in any way to the character ofthe pressure imposed upon the liquid within the tank T or to the mannerwhereby such pressure may be created.

From the foregoing description, it is thought to be obvious that adevice constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof, and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation ofthe several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim 1. In combination with the blow-off cock of a locomotive and itsnozzle, a pipe leading from a source of liquid under pressure anddischarging into said nozzle, a valve interposed in said pipe, means foropening and closing the blow-off cock, and coacting means carried by thevalve in the pipe and said last named means for opening the valve in thepipe when the blow-off cock is opened.
